Application filed May 22, 1912. Serial No. 698,926.

To (171 whom 031 may concern:

Be it known that I, lVILLIAM NEwsoMn, a citizen of the United States, residing at Richmond, in the county of Henrico and State of Virginia, have invented certain new and useful Improvements in Plows, of which the following is a specification, reference being had therein to the accompanying drawing.

This inventionrelates to plows and more particularly to a sub-soiler attachment to be used in connect-ion therewith.

The invention has for one of its objects to improve and simplify the construction of sub-soilers so as to be comparatively simple and inexpensive to manufacture, and which is so designed as to be readily applied to plows already in use without any alteration in the construction thereof, and which can be readily adjusted to and from operativeposition.

Another object of the invention is the provision of a sub-soiler which can be readily adjusted to work at any depth, and which is capable of being set at the most dangerous pitch, irrespective of the depth of penetration, whereby the draft on the animals can be reduced to a minimum and yet effective work accomplished. t

With these and otherobjects in view, as will appear as the description proceeds, the invention comprises the various novel features of construction and arrangement of parts which will be more fully described hereinafter and set forth with particularity in the claims appended hereto.

In the accompanying drawings, which illustrate one embodiment of the invention,

' Figure 1 is a rear perspective View of a plow with the sub-soiler attachment applied thereto and shown in raised or inoperative'position. Fig. 2 is a side view of the plow showing the sub-soiler in operative position and shown workingat different depths by full and dotted lines." Fig. 3 is a vertical section on line 3-3, Fig. 2. Fig. 4 is a perspective view of the bracket or hanger for securing the attachment to the body of the plow. I S'milar reference characters are employed to designate corresponding parts throughout the views.

Referring to the drawing, A designates the beam of the plow, and'B, the standard to which are secured the moldboard C and landside D, and the handles are designated by E. The" plow may be of any standard construction as the sub-soiler attachment is so designed as to be susceptible of use with the usual types of plows without requiring anv alterations therein.

The attachment comprises a supplemental beam or equivalent element 1 which carries a blade 2 that trails behind the body of the plow. The supplemental beam 1 is attached to the plow body by a bracket or hanger which is vertically disposed and formed at its upper end with a hook 4 or equivalent means for partially embracing the beam A. The hook 4 extends transversely over the beam A and is fastened thereto by a bolt 5 which passes through an opening 6, Fig. 4,

in the upper part of the hanger or bracket 3.

The bracket 3 is divided longitudinally into two members 7 that are spaced apart to receive between them the forward end of the beam 1. The lower end of the bracket or hanger is secured to the .bolt 8, which, as shown in Fig. 3, passes through the handle bars of the plow and is a regular part of the latter. It is merely necessary to take this bolt out, and in re-applying it to pass it through openings 9 in the lower end of the bracket or hanger 3, so that the latter will be rigidly fastened at. both its upper and lower ends. The members 7 have vertically spaced apertures 10 soarranged that the apertures of one member will be horizontally in line with those of the other, said apertures serving to receive a bolt 11 that passes through the front end of the supple The sub-soiler is adapted to be supp ortedi at its rear end and to be raised or lowered to and from operative position by the "following means, which is carriedby the han- 100 dles E of the plow. Secured by clips or bolts 12 to the handles are spaced parallel cross-bars 13. and extending from one to the other and secured centrally thereof is a lever supporting bracket 14. On this bracket is fulcrumed a lever 15 which swings back and forth along a toothed sector 16 which is also fastened to the cross-bars 13, there being a spring-pressed'latch 17 on the lever that engages the toothed sector for holding the lever in different positions. This latch can be released byfpressing the member 18 by the hand that grips the handle 19 of the operating lever. The lower end. of the lever is connected by link-forming bars pr rods 20 with the supplemental beam 1 at the rear portion thereof.

The arrangement of the link 20 and operating lever is such that by throwing the handle end of the lever forwardly, the subsoiler can be raised from an operative position, as shown in Fig. 2, to an inoperative position shown in 'Fig. 1, and by reverse movement, the sub-soiler can be thrown to a position for operation. The adjustment of the lever 15 is determined by the adjustment of the front end of the supplemental beam 1 on the sub-soiler. When the supplemental beam is fastened to the lowest point on the hanger or bracket 3, the lever 15 will be in its raised position, as indicated by full lines in'Fig. 2, this posit-ion of the lever corresponding to the proper set of the sub-soiler for deep. sub-soiling. When shallower sub-soiling is desired,,the' front end of the supplemental beam 1 will be attached at a higher point to the hanger or bracket 3 and the set of the lever 15, when in proper operative position, will be forward of the full line position, Fig. 2, as shown for instance by the dot-ted line position. By thus adjusting both the front and rear ends of the sub-soiler, the proper pitch can be maintained for carrying on the sub-soiling operation without any undue drag on the animals.

From the foregoing description, taken in connection 'with the accompanying drawing, the advantages of the construction and of the method of operation will be readily apparent tothose skilled in the art to which the invention appertains, and while I have described the principle of operation of the invention, together with the device which Inow consider to be the best embodiment thereof, I desire to have. it understood that the device shown is merely illustrative, and that such chan es may be made when desired as are wigiin the scope of the claims appended hereto.

, Having thus described theinvention, what I claim as new is l. The combination of a plow including a beam, a plow body, and handles, with a subsoiler attachment comprising a bracket secured at its upper end to the beam and at its lower end between the mold board and land side of the plow body, a bladecarrying supplemental beam having its front end adjustably attached to the bracket, an operating lever mounted on the handles, a link connecting the lever with the rear portion of the supplemental beam, and a device for holding the lever in difierent .positions for controlling the depth of penet'i'ation of the sub-soiler.

2. The combination of a plow including a beam, a plow body, and handles, with a sub-soiler attachment including front and rear supporting devices, and a supplemental beam adjustably carried by both of said devices, the front supporting device comprising a bracket havlng a hook at its upper end engaging the said plow beam and provided with a portion extending downwardly between the moldb'oard and landside of the plow body, means for securing the lower end rigidly with respect to the plow body, and means foradjusting the position of attachment of the supplemental beam to the bracket.

3. The combination'of a plow including a beam, a plow body, and handles, with a sub-soiler attachment including front and rear supporting devices, and a supple-- mental beam adjustably carried by both of said devices, said rear supporting device comprising a lever fulcrumed on the handles above-the rear portion of the supplemental beam, 2. linkconnecting the lever with the rear portion of the supplemental beam, and means carried by the handle for holding the lever in different positions of adjustment.
